摘 要:文章针对平流层飞艇驻空阶段航迹规划问题进行研究和仿真分析。考虑平流层飞艇自身飞行的特点,建立其运动学方程和风场模型,并在适当假设基础上,构造能够反映其飞行能耗的代价函数。最后采用遗传算法进行算例计算,求解平流层飞艇最优轨迹。仿真结果表明,遗传算法能够有效、快速地收敛并稳定至问题的最优解;其所构造的代价函数能够反映飞艇自身飞行特点,并敏感于外界风场环境。Research and simulation analysis of route planning of stratospheric airships were carried out in the paper.Firstly,considering the stratospheric airship' s flight characteristics,its motion equations and wind models were established.Then a cost function of the airship flight energy consumption was formulated based on proper assumptions.Finally,the approach of genetic algorithm was presented for searching optimal route.The example numerical simulations showed that the genetic algorithm was able to quickly,stably converge to the optimal solution,and it was an effective approach for solving this kind of problem;the cost function made in this paper could reflect airship' s flight characteristics and it was sensitive to the wind environment.
